Abstract

Optoacoustic method is a very useful tool for studying laser induced processes in hard dental tissues. In principle, the method can also be used for on-line monitoring of laser drilling. Our study, however, shows that at high laser energies the optoacoustic energy is not proportional to the volume of the ablated hard dental tissue. In addition, the optoacoustic signal depends critically on the presence of water on the tooth surface. These observations must be taken into account when attempting to use the optoacoustic method for on-line monitoring of the laser drilling process.
